The wire drawing cone is similarly driven and is either complete or assembled from several drawing shillings. The wire to be processed is guided through a die into the smallest diameter section of a wire drawing cone and from this section through another die into the smallest diameter section of a second wire drawing cone. The wire rod is guided from this position through the next die to the next largest diameter section of the first wire drawing cone, and then through the other dies to the next largest diameter section of the second wire drawing cone, and so on, until the desired amount is reached. Achieve a wire diameter of Generally, a wire drawing device consists of several sets of wire drawing cords.

-490 (1974) already proposed the use of zirconium dioxide for drawing tire cords and galvanized wire. However, the structural strength of aluminum oxide and zirconium oxide against the surface pressure and friction caused is still very low, and these materials
In the meantime it has become clear that even additively acting temperatures cannot be used in all cases. The insufficient structural strength of ceramic materials is responsible for the wear resistance which is not completely satisfactory in any case. Therefore, even if the damage in the near-surface area of a wire drawing tool made of ceramic material is minimal, as a result of this damage, damage will be induced in the surface area of the wire drawn through the wire drawing tool. In this case, this damage has a very disadvantageous effect, especially when processing coated L-shaped wires. In the production of so-called tire cords, which are usually produced from steel wire coated with silver, there is an additional requirement from the tire manufacturing industry that the metal wire produced has a minimum amount of oil and fat residues on its surface.

点は不十分な耐食性である。Oil and fat residues are inevitably generated from the wire drawing liquid used in the wire drawing process. If the amount of oil and fat residue exceeds the required low value, the metal wire cannot be incorporated into the rubber material as desired in tire production. A problem arises. Therefore, wire drawing fluids with very low oil and fat contents are used when producing tire cords. However, this significantly impairs the usability of wire drawing tools made of zirconium dioxide.
Due to the high abrasiveness, economical operation is no longer possible. Therefore, in this particular field of the wire drawing industry, a makeshift solution is made by using wire drawing tools made of hard steel or with a hard metal membrane. The drawback of this wire drawing tool is insufficient corrosion resistance.

The problem arises of disclosing a wire drawing tool which makes it possible to work with liquids with low oil content without impairing the quality of wire drawing.

。The reason why a wire drawing tool made of silicon carbide is highly suitable for the method of drawing a coated metal wire is believed to be the good thermal conductivity and the high hardness of silicon carbide. Due to the good thermal conductivity, the naturally occurring heat is conducted into the wire drawing liquid and therefore virtually no thermal stresses resulting in damage to the tissue structure occur.

で傷のない鋼線材が伸線加工装置から搬出される。Therefore, not only is a smooth surface obtained when the wire-drawing tool is put into operation with an Ra<0.05 μm, expressed as an average roughness, but it is further increased during the wire-drawing process. The completely flat surface of the wire drawing tool makes it possible to draw highly sensitive and deformable metal wires coated with so-called ductile metals, especially steel wires with a flat and scratch-free surface with coatings based on copper-zinc alloys. It is carried out from the wire processing equipment.

きる。By using wire drawing tools made of silicon carbide, it is possible to use emulsions with low oil and fat content, such as those commonly used when drawing wire rods for the tire manufacturing industry, when drawing metal-coated wire rods. Some things are amazing. Therefore,
The drawn metal wire has the desired low oil residue content on its surface and also provides the desired high throughput corrosion protection due to its scratch-free surface. At the same time, the present invention eliminates the drawback of very low corrosion stability, which occurs with wire drawing tools made of hard steel or with a hard metal coating, such as those conventionally used in the drawing of so-called tire cords. I can do it.
